Patent GB-2061980-A (GB)
Title: Method for the preparation of vinyl chloride resins by suspension polymerization
IPC: C08F14/00
Filed: 1980-10-20
Abstract: The invention provides means for preventing polymer scale deposition on the reactor walls during the suspension polymerization of vinyl chloride monomer in an aqueous medium.The method of the invention comprises (a) coating of the reactor walls, prior to polymerization, with an aqueous coating solution containing an organic dye having sulfonic acid groups or carboxylic acid groups in the alkali metal or ammonium salt form or an alkali metal or ammonium salt of an organic sulfonic acid or carboxylic acid having at least one pair of conjugated double bonds per molecule, followed by drying, and (b) adding a water-soluble thiocyanate to the polymerization mixture. Previously, the use of an organic peroxide with a relatively large solubility in water as initiator in the reaction had led to large scale deposition on the reactor walls but this is avoided under the conditions specified above. Use of such an organic peroxide is advantageous in improving the thermal stability and initial colouring of the resin products.

Title: Stepwise Advance Device for a Cam Programmer
IPC: H01H43/10
Filed: 1980-12-12
Abstract: A stepwise advance device (6) engaging a pinion (8) of the cam pack (5) of a programmer, has a time-delay memory wheel (10) which is intermittently driven in reverse by clutch means (25-28) when the stepping advance means (6) is disengaged at the start of a pause period as by cam (16) on a fast cam 18. The memory wheel (10) has a stepped profile (20) co-operating with an enabling lever (21) in combination with projections (24) of preselected lengths on a time-delay cam (23) on the cam pack (5) to determine the angles of reverse rotation. The number of steps of the profile (20) determines the number of different pause times which can be obtained, while the height of the projections (24) of the time-delay cam (23) determines the duration of each pause time by limiting the reverse rotation of the wheel 10 and thereby the number of teeth (9) which must be stepped forward by the advance device (6) before it drops back onto the pinion 8 to advance it to the next step. <IMAGE>

Title: Liquid Fuel Injection Pumping Apparatus
IPC: F02D41/40
Filed: 1981-01-21
Abstract: A liquid fuel injection pumping apparatus has an axially movable distributor member 28 whereby the amount of fuel delivered by the apparatus can be varied.

Title: Ultrasonic Imaging Devices
IPC: G01S15/32
Filed: 1981-02-05
Abstract: A detector (30) (a Sokolov tube) responds to a pattern of acoustic radiation reflected by echo sources in an ensonified field of view to generate a corresponding pattern of electrical signals. The ensonifying radiation, modulated in accordance with two complementary modulation sequences of equal peak amplitude (ao) and varying respectively linearly and inversely with time, is transmitted simultaneously in respective channels (A and B) at different frequencies. Radiation received at the detector is demodulated at (31, 32). The amplitudes of signals, received (A and B), corresponding a selected echo source in the field of view, are divided at 33 and then processed at circuits (34, 35) to generate an output signal indicative of the range of that echo source. <IMAGE>

Title: Load weighing device for cranes
IPC: G01L5/04
Filed: 1981-04-01
Abstract: A load weighing device for cranes in which a dynamometer interposed in the crane rope measures the tension in the rope when a load is supported by the crane hook. The output signal from the dynamometer is passed to a peak detector and memory circuit. The output signal from the dynamometer, shown as curve 1 shows that the tension in the rope during static suspension of a load is different according to whether the immediately preceding movement of the load was upwards (B to C) or downwards (D to E). This can lead to false reading being passed to an associated safe load indicator. The output from the peak detector and memory is shown in curve 2 and will be seen to err on the safe side irrespective of the direction of rope motion; the peak value B is maintained until the rope tension falls below a predetermined level, e.g. 75% of the peak value. It is this output (i.e. curve 2) that is thus passed to the safe load indicator. <IMAGE>
Patent GB-2082624-A (GB)
Title: Method of gas production
IPC: C21B13/02
Filed: 1981-08-13
Abstract: Gas is produced in a ferrous bath reactor 20 containing an iron melt 21 by feeding solid or liquid carbonaceous fuel (e.g. coal) 24 into the reactor 20, and blowing an oxygen-containing gas from nozzles 26,27 onto the surface 22 of the melt to gasify the fuel. The gas is collected in a space 30 through which the gas from the nozzles 26,27 is blown. In traversing the gas space 30, the gas from the nozzles 26,27 causes partial combustion of the generated gas so that the combustion gases are transported to the melt surface 22 whereby the combustion heat is transmitted to the melt 21. <IMAGE>

Title: Improvements relating to fast focussed electron multiplier tubes
Inventor: SIVYER RAYMOND FRANK
IPC: H01J9/12
Filed: 1981-12-05
Abstract: Fast focussed electron multiplier tubes include arrays of electron emitting dynodes, which typically possess coated secondary electron emitting surfaces. A manufacturing method is disclosed which achieves efficient in-situ coating of these surfaces without subsequent undue disturbance of the electron tube optics. Two facing dynode assemblies (6,6') include trough-shaped dynodes (20,22). At least one dynode (20) includes a wire (not shown) spanning the length of the trough- shape and located on an equipotential (31) between facing dynodes (20,22) such that the tube function is substantially unaffected thereby. A spot (10) of secondary emitting material is provided on the wire and when a radio frequency field is applied to the tube, currents developed in the wire cause the spot to evaporate thereby coating the facing dynodes (20,22). <IMAGE>
Patent GB-2090433-A (GB)
Title: Production of control signals for steering a projectile
IPC: G05D1/10
Filed: 1981-12-16
Abstract: Steering commands for intermittently operated steering control devices on a projectile which rolls about its longtudinal axis, are represented by a periodic signal referenced to the roll rate of the projectile, with an amplitude corresponding to the magnitude of the command and a phase corresponding to the operation direction of the command with respect to a reference position of roll of the projectile. In the method at each transition of the command signal through zero a function signal is generated which intersects the command signal at two points symmetrical about the peak value, the interval between the points being proportional to the amplitude of the control signal, and the directional control signal which includes correction signals generated by an internal regulating system is generated during the interval.

Title: Improvements in or relating to absorption of pollutant material from a polluted gas
Inventor: ASHLEY MICHAEL JOHN
IPC: B01D53/34
Filed: 1982-02-25
Abstract: In a method of absorbing pollutant material e.g. sulphur dioxide from a polluted gas, an aqueous suspension of a solid absorbent e.g. calcium hydroxide is sprayed into the gas; and the ambient conditions in the gas are such that all the water is evaporated and the absorption product is dried as it is formed. The spray droplet size is controlled to be a practical maximum consistent with maintaining the ambient conditions. The spray droplet size may be so controlled that the arithmetical average spray droplet lifetime is at least 80% of the theoretical maximum spray droplet lifetime consistent with maintaining the ambient conditions.

Title: Disc player having self-actuated magnetic clamping device
Inventor: SCHATTEMAN ETIENNE ARTHUR MARI
IPC: G11B17/035
Filed: 1983-02-07
Abstract: A magnetic clamping device (22) for a disc player has an annular permanent magnet (76) with a permeable flux shorting washer (77) secured to the top of the annulus so that the magnetic flux from the magnet is emitted from the bottom of the annulus. When the player housing (30) and disc spindle (25) are oriented for disc insertion, the device is levitated in a raised resting position by a levitating ring (78) of permeable material fixed to the upper part of the player housing. When the housing and spindle are oriented for playing a disc (20) a permeable disc driving plate (35) comes closer to the magnet the magnetic flux from which becomes linked to the plate for disc clamping. The clamping device changes position when the centering hub of the spindle engages with the disc central aperture, to that the device is always clear of the disc while the disc is inserted or ejected. <IMAGE>
